Purpose: Cost-benefit analysis is one of the most commonly used economic evaluation methods, which helps to inform the economic value of a program to decision makers. However, the selection of a correct benefit estimation method remains critical for accurate cost-benefit analysis. This paper compared benefit estimations among three different benefit estimation models. Methods: Data from community-based chronic hypertension management programs in a city in South Korea were used. Three different benefit estimation methods were compared. The first was a standard deterministic estimation model; second, a repeated-measures deterministic estimation model; and third, a transitional probability estimation model. Results: The estimated net benefit of the three different methods were $1,273.01, $-3,749.42, and $-5,122.55 respectively. Conclusion: The transitional probability estimation model showed the most correct and realistic benefit estimation, as it traced possible paths of changing status between time points and it accounted for both positive and negative benefits.

The imports of used medical equipment such as CT. MRI have been rapidly increased every year. How to manage those medical equipment has been one of critical issues in the government sector. In this study, we demonstrate how benefit/cost analysis using the Analytic Hierarchy Process (AHP) can be applied to the comparison of used CT/MRI and new CT/MRI. The final results show that the new CT/MRI is more attractive than the used CT/MRI.

소비자들이 왜 위조품을 시용할까? 하는 의문에서 출발하였다. 사전조사를 통해 위조품 사용동기, 사용혜택 및 사용손실 척도를 제작한 후, 이러한 위조품사용 동기요인과 위조품사용 혜택요인 및 위조품사용 손실요인 각각에 대해 한중소비자간에 인식의 차이가 있는가를 확인하였다. 연구결과 첫째, 위조품 사용동기요인은 과시성, 경제성, 만족감, 실용성의 4가지로 나타났으며, 한중소비자의 인식차이를 알아본 결과 과시성, 경제성과 만족감 요인에서는 유의미한 차이가 나타났다. 둘째, 위조품 사용 혜택요인은 개인적 혜택과 경제적 혜택의 2가지로 나타났다. 2가지 혜택요인 모두에서 한중소비자간 유의미한 인식차이가 나타났으며, 한국소비자가 중국소비자에 비해 높은 긍정응답을 나타내 보였다. 셋째, 위조품사용 손실동기요인은 개인적손실, 품질손실, 물질적손실 및 사회적손실의 4가지 요인으로 나타났다. 개인적손실과 품질손실 및 물질적손실요인에 대해 한중소비자간 유의미한 인식차이가 나타났다. 이러한 연구결과는 한국소비자의 위조품사용행동에 대한 심층적 이해를 통해, 향후 위조품 사용을 줄이는 공공 캠페인에 활용할 수 있는 자료를 제공해 줄 것으로 기대한다.

This study delivers the actual condition of investment for industrial accident prevention based on survey of 500 construction sites from 'reports far industry safety and health' published by Korea Occupational Safety & Health Agency (KOSHA). The various research techniques were used such as technical statistic analysis for construction industry, cost comparison of industrial accident prevention and accident loss. A formula was deduced to calculate accident loss and accident frequency by accident prevention cost through regression analysis.

Purpose: The purpose of this study was to use cost-benefit analysis of activity to clarify the economic effect of prepared nurses versus atmospheric environment managing engineers as healthcare managers. Methods: For the study 111 workplaces were surveyed, workplaces in which nurses or atmospheric environment managing engineers were employed as healthcare managers. The survey content included annual gross salaries, participation in external job training, costs in joining association covered by the company, location and year of construction of the healthcare office, various kinds of healthcare expenditures, costs in operating healthcare office, health education, and activity performance in the work of environment management. Results: In the case of the healthcare manager being a nurse, benefit was larger than input costs at a ratio of 2.31. On the other hand, in the case of healthcare manager being an atmospheric environment managing engineer, input costs were larger than benefits (benefit-cost ratio 0.88). Conclusion: Results indicate that nurses are an effective healthcare human resource and can offer good quality healthcare service. Therefore companies should hire nurses and actively promote the economic efficiency of nurses in workplace.

Objectives: An objective of this study was to perform a risk assessment and social cost-benefit analysis for revising permissible exposure limits for seven substances: Nickel(Insoluble inorganic compounds), benzene, carbon disulfide, formaldehyde, cadmium(as compounds), trichloroethylene, touluene-2,4-diisocyanate. Materials and Methods: The research methods were divided into risk and hazard assessment and cost-benefit analysis. The risk and hazard assessment for the seven substances consists of four steps: An overview of GHS MSDS(1st), review of document of ACGIH's TLVs (2nd), comparison between international occupational exposure limits and domestic permissible exposure limits(3rd), and analysis of excess workplace and excess rate for occupational exposure limits based on previous work environment measurement data(4th). Total cost was estimated using cost of local exhaust ventilation, number of excess workplace and penalties for exceeding a permissible exposure limit. On the other hand, total benefit was calculated using the reduction rate of occupational disease, number of workplaces treating each substance and industrial accident compensation. Finally, the net benefit was calculated by subtracting total cost from total benefit. Results: All the substances investigated in this study were classified by CMR(Carcinogens, Mutagens or Reproductive toxicants) and their international occupational exposure limits were stricter than the domestic permissible exposure limits. As a result of excess rate analysis, trichloroethylene was the highest at 11%, whereas nickel was the lowest at 0.5%. The excess rates of all substances except for trichloroethylene were observed at less than 10%. Among the seven substances, the total cost was highest for trichloroethylene and lowest for carbon disulfide. The benefits for the seven substances were higher than costs estimated based on strengthening current permissible exposure limits. Thus, revising the permissible exposure limits of the seven substances was determined to be acceptable from a social perspective. Conclusions: The final revised permissible exposure limits suggested for the seven substances are as follows: $0.2mg/m^3$ for nickel, 0.5 ppm(TWA) and 2.5 ppm(STEL) for benzene, 1 ppm(TWA) for carbon disulfide, $0.01mg/m^3$(TWA) for cadmium, 10 ppm(TWA) and 25 ppm(STEL) for trichloroethylene, 0.3 ppm(TWA) for formaldehyde, and 0.005 ppm(TWA) and 0.02 ppm(STEL) for toluene diisocynate(isomers).

멀티태스킹은 이제 일상이 되었다. 자발적으로 하고 있던 일을 중단하고, 다른 것으로 전환하는 행동이 점점 쉬워지고 잦아지고 있다. 그러나 기존 연구에 따르면 과제전환은 대부분 인지적 비용을 야기시킬 뿐이다. 본 연구에서는 자발적 과제전환으로 인지적 이득을 얻을 수 있는지에 대해서 알아보고자 하였다. 이를 위해서 우선, 실험 1에서는 비슷한 성격의 두 과제를 할 때, 기존 연구와 마찬가지로 과제전환빈도와 수행도에 부적상관관계가 나타남을 확인하였다. 실험 2에서는 과제전환 가능 조건과 불가능 조건을 나누고, 개인의 멀티태스킹 선호도와 미디어 멀티태스킹 지수에 따라 각 과제의 수행도와 주관적 평가가 어떻게 달라지는지를 분석하였다. 실험 결과, 기존의 대부분 연구와 다르게 과제전환에서 항상 손실이 나타나는 것은 아니었다. 특히, 멀티태스킹 선호도가 높은 집단에서는 자발적 과제전환에서의 이득이 더 크게 나타났다. 기존의 과제전환 연구는 주로 손실이 발생하는 이유와, 그것을 줄이는 방법에 집중된 경향이 있었다. 그러나 본 연구는 과제전환 행동에서 발생하는 인지적 손실 뿐만 아니라 이득도 살펴보고자 하였다. 그 결과 참가자내 조건과 과제의 특성에 따라 손실과 이득이 차이 나는 것을 확인하였다.
